Try searching for .NRG files - they are usually stored in a TEMP folder.

I don't use Nero but - In Nero, new selection, select DVD copy, first tab (labelled 'Image') shows location of temp NRG file (and its name)...directly underneath that is a box, "Delete image file after disc copy".

I found out exactly the area you are talking about, and the delete after burning box is already checked. But that is in Burning Rom. I used Nero Express. Whether it is all interlinked I don't know.

I had copied an image to the computer but did not burn it, so I assume it is still on the system somewhere. I uspect it's the 532mb file I mention below.

I did locate the NRG file which is 532mb in size. I tried opening it but it needs some different software to open. If I delete the file all that happens is my DVD disc isn't recognised when trying to copy an image to it. So I suspect it is part of the Nero software. Fortuntely I had'nt got rid of it completely and managed to 'restore' it.

Still, I would like to find that old image file and get rid of it if possible.
